2000 peaker revision

I reworked the debt section to eliminate tranche 1. Tranche 2 now amortizes
years 1-10 and pays 11% interest. Tranche 3 amortizes years 11-20 with
interest of 11.2%. I re-solved for optimal amortization schedules and face
amounts to get a minimum coverage ratio of 2.25x and an average coverage of
3.25x.

I removed some references to the amortization of the power contract that
Jinsung pointed out. I also re-hardcoded the state franchise tax for Gleason.

Let me know what else needs re-working.
